Tularemia is more common in males, possibly because of a greater likelihood of exposure through hunting and landscaping. Tularemia occurs in persons of all ages, but is most common in children.

Tularemia is more common in the months of May through September. Bites from infected ticks or deer flies usually occur in the summer months, but illness due to animal handling and hunting can occur at any time of the year.
